( when the area is numbed with a local anaesthetic we are able to use higher power settings on the Laser and also can undertake curettage (cut out) where appropriate therefore providing a much more invasive treatment. This will significantly reduce the chances of having to repeat the procedure in the event of incomplete resolution. Without a local anaesthetic lower power settings have to be used and curetttage can not be undertaken therefore will require at least 2 or 3 sessions to provide high rates of efficacy )
